The Hemi block has eight steam holes near the lower head bolt holes. The wedge block does not have these steam holes. The block pictured above is correct for a wedge block and does not have the Hemi steam holes.

The wedge industrial blocks had these steam holes.

The later stock 440 blocks had the steam holes, especially the 440-3 motor home and truck blocks scope
